 Since the early 1980s there is a constant ecological problem due to the massive pollution of the bay as a result of the polluted waters of the Topčiderka river which flows into the bay.The garbage and highly polluted silt fills the bay and creates shoals.During low-tide, the bay is unusable for the boats in the marina, located in the middle of the bay or for the kayakers of "Partizan" and "Crvena Zvezda" who use the bay for practice.
